Change allocation unit from cylinder to megabyte or tracks for a better release

To avoid loosing space when customer allocate file in cylinder unit, it should be great to have a properties on dataclas to convert automatically cylinders unit allocation to tracks or megabytes. In this way the space release is done at tracks bou...

ACS Read only variable required for RECFM

We are converting our sequential data to extended format in preparation for pervasive encryption. We use the zbna software to identify files unsuitable for EF, due to utilising EXCP. We have identified a lot of files with a RECFM of FS (mostly SAS...

DFSMS and improved volume selection in a Storagegroup.

Any installation changes volume size over the years. From M3 to M54 and now many of us use EAVs as well.So the storagegroups is typically a mix volumes with different sizes; from a few GBs to many GBs. The key criteria for SMS volume selection und...

Use of a filtlist in the exclude statement

We would like to be able to use a filltlist in the exclude statement of another filllist. Often we have a long list of datasets that are allocated with custom constructs. So that the general filtlist does not unintentionally take effect, we also e...

DFSMS, SREAD OVER VOLUMES depending upon volume-status and free-space

'Spread over volumes' allocated always on the volumes at the beginning of a storagegroup, regardless of volume-status : QUINEW,ENABLE and free-space. If it supported the behavior of primary allocation over multiple volumes no longer differs from o...

Communication between SMSPLEX-Members about ACDS error

If a member of an SMSPLEX Fails to read or write the ACDS, it should not just completely fail and activate a null configuration.Instead, it should inform the other members of SMSPLEX about this failure, so the other members can identify if ALL mem...

EAV impacting Overflow storage group usage

Due to the introduction of EAV volumes in our environment, the number of volumes in our primary storage groups will be reduced such that the number of volumes in the overflow pool can have more than the number of volumes requested for an allocatio...

Enhance DFSMS to check for assignment of DATACLASS values for the SCDS, ACDS, & COMMDS

This will inform administrators prior to an activation that a configuration conflict exist which may cause activation to go into allocation, effectively preventing activation from proceeding. Worse case could be a difficult to recover CDS file.
